What does Keepass do that pass doesn't?
I've only used keypassx on windows, but the auto fill feature was amazing. You would push a key shortcut, then based on the window title of whatever window has focus, it would simulate key presses into it. So I could type secure credentials into any program on my computer with one key stroke.
It works and is better than placing password in clipboard and than "xdotool type $pass". Likely worse than proper integration with password consumer.
